#NOT ABLE TO JOIN SKYPE MEETING FOR MAC#
Let’s assume that you want to troubleshoot issues that occur when users try to join a Skype for Business Online (formerly Lync Online) meeting by using Lync 2010, Lync 2013, the Lync for Windows Store app, or Lync for Mac 2011. Below are the instructions provided by Microsoft: Microsoft has developed detailed instructions for IT administrators to diagnose the issues and fix the problems based on the root causes. I enabled SIP debugging on the Trios and compared a Teams meeting (fail) vs a Skype meeting (success) and the only difference is the following two lines.With the many different types of endpoints and network configurations that organizations use, there can be different ways that users connect to their Skype for Business environment, and as such, different sources of issues when connecting. I guess this could be caused by our Palo but it seems odd so curious if anybody else has saw anything simliar in their environment? It seems like the the combination of Teams & NAT just doesn't play nice with a Trio. We tried configuring the Trio NAT settings on "Settings" -> "Network" -> "NAT" by inputing the external address that the trio gets NAT'ed to but no luck. However this is not a practical solution for us due to the number of Trio's we have. When we assign the Trio's a public address the Teams call works fine. After further troubleshooting & testing we found that the issue was actually being cause by NAT. We use a Palo Alto firewall and after packet captures/logs we found that no traffic was being blocked/denied by the palo.

Our initial troubleshooting invovled bringing a Trio off our network to try to isolate the problem and I found that from my house a Trio (with same exact configuration, no changes) was indeed able to join a Teams meeting successfully. Note that all the Trio's work perfectly when using a Skype Meeting. We have various firmware versions on our Trio's including 5.7,5.8, and 5.9 and the behavior is the same on all of them. Upon clicking "join" the Trio attempts to join the meeting but after a few seconds it disconnects (see attached video "Trio_Video"). We have 50+ Trio's and they all are having the same issue when involved in a Microsoft Teams meeting.
